Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an air conditioner in which a panel is attached to the main body, the panel being almost entirely a ventilation surface.

(b) Conventional technology Conventionally, an example of the structure of an air conditioner in which a panel with almost the entire ventilation surface is attached to the main body is the Utility Model 57.
-35800 publication discloses one.

According to this content, vertical blades are provided in the air outlet passage on the front surface of the main body, and horizontal blades are provided in the air outlet of the panel located on the leeward side of the air outlet passage. Then attach this panel to the front of the main unit. By moving the vertical and horizontal blades, the direction of the air discharged from the outlet was changed.

(c) Problems that the invention aims to solve In an air conditioner with such a structure, one (horizontal) blade is located inside the other (vertical) blade, so the operation of the other blade is difficult. There was a problem that I found annoying.

The purpose of the present invention is to incorporate blades that change the wind direction in the vertical and horizontal directions into a thin panel.

(d) Means for solving the problem In order to achieve this objective, the present invention provides a panel attached to the main body with a plurality of ventilation holes separated by partition plates, and each ventilation hole is equipped with a ventilation grill. A plurality of ventilation grills are provided along this partition plate, and these ventilation grills are rotatably supported by the partition plate.

(e) Effect Each ventilation hole provided in the panel is reinforced with a partition plate,
This allows the total area of the ventilation holes to be increased.
Further, a plurality of ventilation grilles are provided along the partition plate, and by operating the grilles, the air discharged from the ventilation openings can be individually changed into arbitrary directions within the ventilation openings.

(f) Example In the drawing, 1 is a window type air conditioner,
It is composed of an outer box 2, a main body 3 housed in the outer box, and a front panel 4 attached to the front surface of the main body.

As shown in FIG. 2, the main body 3 is divided into an indoor chamber A and an outdoor chamber B by a partition plate 6 erected on a base 5. Reference numeral 7 denotes a fan motor, which is fixed to the outdoor side surface 8 of the partition plate 6, and one rotating shaft 9 of this motor passes through the partition plate 6 and projects into the indoor chamber A. A propeller fan 11 is attached to the other rotating shaft 10. 12 is a slinger ring, which is fixed to the outer periphery of the propeller fan 11, and as the fan rotates, the slinger ring 12
It also rotates to stir up the drain water that has accumulated in the base 5. 13 is an outdoor heat exchanger, 14 is a fan casing, and 15 is a compressor.

16 is an indoor heat exchanger, 17 is a Sirotskov fan fixed to one rotating shaft 9, and 18 is a casing of this fan. As the fan rotates, indoor air is sucked in from the suction port 19 of the casing and guided to the indoor heat exchanger 16. I'm trying to tremble.

As shown in FIG. 3, the front panel 4 is almost entirely made up of ventilation holes, and the inside of the panel is divided into four sections by vertical bars 20 and horizontal bars 21, and a suction surface 22 is provided at the lower left. is formed. The height dimension a of the upper left blowing surface 23 is smaller than the height dimension b of the lower left blowing surface 24, and these blowing surfaces 2
Three grills 25 and 26 (hereinafter referred to as upper and lower wind direction changing frames) are installed in rows 3 and 24, respectively. Reference numeral 27 denotes a support pin that projects from the upper surface 28 of the upper air direction changing frame 25 and is engaged with the upper frame 29 of the front panel 4. 30 is the upper wind direction change frame 25
It is a connecting pin that protrudes from the bottom surface of the , and is shaped like a square prism. Reference numeral 31 denotes a wind direction changing blade that vertically changes the wind discharged from the upper wind direction changing frame 25, and its both ends 32 are engaged with the left and right inner walls 33 of the upper wind direction changing frame. Reference numeral 34 designates a connecting plate for these wind direction changing blades, and the leading edge thereof has a V-shaped notch 35, into which a rotating shaft 36 at the center of each blade is inserted.

Reference numeral 37 denotes a connecting tube projected from the upper surface of the lower air direction changing frame 26, into which the square column connecting pin 30 is fitted. Further, a support pin 38 is protruded from the lower surface of the lower air direction changing frame 26, and is engaged with the lower frame 39 of the front panel 4. Reference numeral 40 denotes a wind direction changing blade that vertically changes the wind discharged from the lower wind direction changing frame 26, and its both ends 41 are engaged with the left and right inner walls 42 of the upper wind direction changing frame. The blades are connected by a connecting plate 34. Then, the connecting pin 30 of the upper wind direction changing frame 25 is inserted into the connecting tube 37 of the lower wind direction changing frame 26, and both are assembled integrally. , the support pin 27 of the upper wind direction change frame 25, the connecting cylinder 37, and the support pin 38 of the lower wind direction change frame 26 are respectively attached to the lower frame 39, and the wind direction change frames 25, 26 are positioned in these openings 23, 24. . When the front panel 4 assembled in this way is attached to the front of the main body 3, the suction grill 22
is in front of the nozzle 19 of the casing 18, and an operation switch 44 faces the opening 43 in the upper left corner.
The wind direction changing frames 25 and 26 are located in front of the indoor heat exchanger 16.

In an air conditioner with such a configuration,
When the Sirotskov fan 17 is rotated, indoor air is sucked into the suction grill 22 and then into the casing 18.
and is blown onto the indoor heat exchanger 16. At this time, the speed of the air flowing inside the casing 18 increases as it goes upward from the nose portion 45 of the casing 18. Therefore, the speed of the wind discharged from the upper wind direction changing frame 25 of the front panel 4 is
The speed is higher than the speed of the wind discharged from the lower wind direction changing frame 26. Then, when the lower wind direction changing frame 26 is swung in the left-right direction, the upper wind direction changing frame 25 is also swung in the same direction along with this swinging. Further, the vertical wind direction changing blades 31 and 40 disposed within these wind direction changing frames 25 and 26 individually swing up and down. In this air conditioner 1, the right half of the front panel 4 is used as an air discharge part, so the area of this discharge part is widened, the ventilation resistance is reduced, and the air sucked into the main body 3 is quickly discharged into the room. In addition, wind direction changing frames 25 and 26 are arranged in the air discharge section having a large opening area.
Since these modified frames were attached to the front panel 4 by being supported by the horizontal crosspiece 21 that partitions the discharge section (ventilation port), that is, the partition plate, and the frames 29 and 39 of the front panel 4, these modified frames and blades are attached to the front panel. It is easy to operate from the front of the panel 4.

Incidentally, in the above embodiment, a suction surface was formed on the front panel, but this suction surface may not be provided.

(g) Effects of the invention As mentioned above, this invention provides the ventilation openings of the air conditioner panel with a partition plate that partitions the ventilation openings, thereby reinforcing the ventilation openings and reducing the total area of the ventilation openings. It is possible to reduce the ventilation resistance of this air conditioner. Further, since a plurality of ventilation grilles are provided along the partition plate in this ventilation hole, the direction of the air discharged from this ventilation hole can be arbitrarily changed by operating the ventilation grill in each ventilation hole.
Furthermore, since the ventilation grilles are supported by the partition plate of the panel, they can be easily operated from the front of the panel.
